An anonymous reader shares a report: Scientists have been working on creating synthetic blood for years now. The hope is that this substance will have a longer shelf life than human blood -- which can only be refrigerated for 42 days -- and eventually can be packaged and stored for use in emergencies. If this works, thousands of lives could be saved every year. "People can't show up fast enough and then the system can't draw their blood fast enough to meet the need," said Allan Doctor, a physician and researcher at the Washington University in St. Louis. Doctor's lab has been working to create a blood substitute called ErythroMer, comprised of human hemoglobin, sourced from the red blood cells in expired blood at blood banks, and a synthetic polymer. This synthetic blood is actually a dehydrated powder, which would allow it to be stored for years, rather than weeks, and easily transported. Doctor envisions that it could eventually be packaged along with purified water so that doctors or EMTs could mix it when they needed to use it on a patient. ErythroMer is still in the planning stages. It has only been tested on animals, and Doctor predicts that the team is about three to five years from the first human trials. Following that, it will need FDA approval, and then healthcare workers will need to be trained to use it properly to avoid infections. "It's important for us to have a bulletproof delivery system," Doctor told me. He predicts that it will be available in six to 10 years if the trials are successful, and if they can make a cost-effective formula. There are different approaches to creating synthetic blood, which is technically just a way of transporting oxygen in the body. In 2013, a team in Romania announced that they were making it with albumin, a liver protein, and hemerythrin, a protein extracted from worms. In the UK, scientists with the National Health Service have been testing lab-grown red blood cells.

An anonymous reader quotes a report from The New York Times (Warning: source may be paywalled, alternative source): Recently, scientists carried out the first large-scale study of what climate change may do to the world's much-loathed parasites. The team came to a startling conclusion: as many as one in three parasite species may face extinction in the next century. As global warming raises the planet's temperature, the researchers found, many species will lose territory in which to survive. Some of their hosts will be lost, too. Researchers have begun carefully studying the roles that parasites play. They make up the majority of the biomass in some ecosystems, outweighing predators sharing their environments by a factor of 20 to 1. For decades, scientists who studied food webs drew lines between species -- between wildebeest and the grass they grazed on, for example, and between the wildebeest and the lions that ate them. In a major oversight, they didn't factor in the extent to which parasites feed on hosts. As it turns out, as much as 80 percent of the lines in a given food web are links to parasites. They are big players in the food supply.

Some researchers had already investigated the fate of a few parasite species, but Colin J. Carlson, lead author of the study and a graduate student at the University of California, Berkeley, and his colleagues wanted to get a global view of the impact of climate change. Some kinds won't lose much in a warming world, the study found. For instance, thorny-headed worms are likely to be protected because their hosts, fish and birds, are common and widespread. But other types, such as fleas and tapeworms, may not be able to tolerate much change in temperature; many others infect only hosts that are facing extinction, as well. In all, roughly 30 percent of parasitic species could disappear, Mr. Carlson concluded. The impact of climate change will be as great or greater for these species as for any others studied so far. The study has been published in Science Advances.

Reader AnalogDiehard writes: Writer Alex Kaseburg has filed a lawsuit against TBS and Time Warner alleging that jokes recited on the Conan O'Brien show were stolen from his blog shortly after they were published. The case gets heard in August and could create new protections in a legal forum in which there is little precedent or clear definition in what defines a joke as "original" and subject to legal protection, especially in an industry where theft of humor occurs on a regular basis. But the outcome of any judicial decision opens a big can of worms and raises serious questions: Will YouTube videos get shut down from DMCA notices citing copyrighted jokes? Will compliance staff have to be retained to ensure that their magazine or news article, TV show, movie, or broadway act is not infringing on copyrighted jokes? Will copyrights on jokes get near-perpetual protection like the controversial Sonny Bono Copyright Extension Act? Will people be able to recite limericks without fear of infringing? Will tyrannical politicians copyright critical jokes to oppress freedom of speech? Will legal cases be filed arguing that a comedian's joke(s) bears too much similarity to a copyrighted joke recited decades ago? Will girl scouts be free to tell copyright jokes around the campfire?

Life expectancies have risen in many countries around the world thanks to breakthroughs in medical treatment and sanitation in the last century. The maximum age of death has also increased. But as these numbers continue to rise, it raises the question as to how long can people live? ABC News reports: The record for the world's oldest person is 122 years and the odds of shattering that record are slim, according to an analysis published Wednesday in the journal Nature. In the new study, researchers [at the Albert Einstein College of Medicine in New York] analyzed mortality data from a global database. They found that while there have been strides in reducing deaths among certain groups -- children, women during childbirth and the elderly -- the rate of improvement was slower for the very old, those over 100 years old. Next they examined how old centenarians were when they died. The record holder is Jeanne Calment, of France, who lived until 122 years old. Since her death in 1997, no one has broken her record. The researchers calculated the odds of someone reaching 125 years in a given year are less than 1 in 10,000. They think the human life span more likely maxes out at 115 years. Some aging specialists said the study doesn't take into account advances that have been made in extending the life span -- and health -- of certain laboratory animals including mice, worms and flies through genetic manipulation and other techniques. The goal is to eventually find treatments that might slow the aging process in humans and keep them healthier longer.

ckwu writes: Polystyrene foams—including products like Styrofoam—are rarely recycled, and the materials biodegrade so slowly that they can sit in a landfill for hundreds of years. But a pair of new studies shows that mealworms will dine on polystyrene foam when they can't get a better meal, converting almost half of what they eat into carbon dioxide. In one study, the researchers fed mealworms polystyrene foam and found that the critters converted about 48% of the carbon they ate into carbon dioxide and excreted 49% in their feces. In the second study, the researchers showed that bacteria in the mealworms' guts were responsible for breaking down the polystyrene--suggesting that engineering bacteria might be a strategy for boosting the reported biodegradation.

An anonymous reader writes: In a cybersecurity survey of 485 large colleges and universities, the Massachusetts Institute of Technology came in at the bottom of the list. In a report released today, SecurityScorecard analyzed the educational institutions based on web application security, network security, endpoint security, IP reputation, patching, and other security indicators. That might not seem intuitive, but according to the linked article, it's not purely mistaken. Some of that low ranking can be chalked up to things like intentional security holes created in the course of researching vulnerabilities, but some of it comes from "exposed passwords, old legacy systems, and a bunch of administrative subdomains that seem to have been forgotten about," as well as pockets of malware.

A brief quote: "Thunderstrike 2 takes advantage of four older, previously disclosed vulnerabilities. These had all been known and fixed on other platforms, but not on Apple's MacBooks. ... Speed Racer (Incorrect BIOS_CNTL configuration, 2014, VU#766164), Darth Venamis (S3 boot script injection, 2014, VU#976132) Snorlax (Flash configuration is not set after S3 sleep, 2013 VU#577140) and PrinceHarming (2015) Unsigned Option ROMs (2007, 2012). ... While we're looking at Apple specifically in this research, the overall message is that many vendors are not keeping up to date and are not responding to CERT, especially if it requires effort to port or test vulnerabilities from other vendor platforms."

BIOS4breakfast writes: Wired reports that later this week at BlackHat and Defcon, Trammell Hudson will show the Thunderstrike 2 update to his Thunderstrike attack on Mac firmware (previously covered on Slashdot). Trammell teamed up with Xeno Kovah and Corey Kallenberg from LegbaCore, who have previously shown numerous exploits for PC firmware. They found multiple vulnerabilities that were already publicly disclosed were still present in Mac firmware. This allows a remote attacker to break into the Mac over the network, and infect its firmware. The infected firmware can then infect Apple Thunderbolt to Ethernet adapters' PCI Option ROM. And then those adapters can infect the firmware of any Mac they are plugged into — hence creating the self-propagating Thunderstrike 2 "firmworm." Unlike worms like Stuxnet, it never exists on the filesystem, it only ever lives in firmware (which no one ever checks.) A video showing the proof of concept attack is posted on YouTube.

It's also capable of hijacking DNS settings. The people controlling the system use it for selling "follows," "likes," and so forth on social media sites like Twitter, Instagram, Vine, Facebook, and Google+. Affected router manufacturers include: Actiontec, Hik Vision, Netgear, Synology, TP-Link, ZyXEL, and Zhone. The researchers found that even some medical devices were vulnerable to the worm, though it wasn't designed specifically to work with them.

An anonymous reader writes: Italian researchers in Trent have enabled 15 Pholcidae spiders to spin graphene-strengthened dragline silk just by spraying them with a solution containing carbon nanotubes and graphene flakes. The resulting fiber is as strong as Kevlar 49, and ranks among the most resilient and ductile in the world of manufacturing. But Emiliano Lepore's research has not succeeded in understanding by what process the spiders are able to incorporate the ambient materials into their webs. Since spider-farming is historically unproductive, the possibility of continuing the research on silk-worms has been presented.

An anonymous reader writes: We've been in a malware arms race since the 1990s. Malicious hackers keep building new viruses, worms, and trojan horses, while security vendors keep building better detection and removal algorithms to stop them. Botnets are becoming more powerful, and phishing techniques are always improving — but so are the mitigation strategies. There's been some back and forth, but it seems like the arms race has been pretty balanced, so far. My question: will the balance continue, or is one side likely to take the upper hand over the next decade or two? Which side is going to win? Do you imagine an internet, 20 years from now, where we don't have to worry about what links we click or what attachments we open? Or is it the other way around, with threats so hard to block and DDoS attacks so rampant that the internet of the future is not as useful as it is now?

mikejuk writes The nematode worm Caenorhabditis elegans (C. elegans) is tiny and only has 302 neurons. These have been completely mapped, and one of the founders of the OpenWorm project, Timothy Busbice, has taken the connectome and implemented an object oriented neuron program. The neurons communicate by sending UDP packets across the network. The software works with sensors and effectors provided by a simple LEGO robot. The sensors are sampled every 100ms. For example, the sonar sensor on the robot is wired as the worm's nose. If anything comes within 20cm of the 'nose' then UDP packets are sent to the sensory neurons in the network. The motor neurons are wired up to the left and right motors of the robot. It is claimed that the robot behaved in ways that are similar to observed C. elegans. Stimulation of the nose stopped forward motion. Touching the anterior and posterior touch sensors made the robot move forward and back accordingly. Stimulating the food sensor made the robot move forward. The key point is that there was no programming or learning involved to create the behaviors. The connectome of the worm was mapped and implemented as a software system and the behaviors emerge. Is the robot a C. elegans in a different body or is it something quite new? Is it alive? These are questions for philosophers, but it does suggest that the ghost in the machine is just the machine. The important question is does it scale?

An anonymous reader writes: Analyzing more than 2,000 Stuxnet files collected over a two-year period, Kaspersky Lab can identify the first victims of the Stuxnet worm. Initially security researchers had no doubt that the whole attack had a targeted nature. The code of the Stuxnet worm looked professional and exclusive; there was evidence that extremely expensive zero-day vulnerabilities were used. However, it wasn't yet known what kind of organizations were attacked first and how the malware ultimately made it right through to the uranium enrichment centrifuges in the particular top secret facilities. Kaspersky Lab analysis sheds light on these questions.

sciencehabit writes You can credit your existence to tiny wormlike creatures that lived 500 million years ago, a new study suggests. By tunneling through the sea floor, scientists say, these creatures kept oxygen concentrations at just the right level to allow animals and other complex life to evolve. The finding may help answer an enduring mystery of Earth's past. The idea is that as they dug and wiggled, these early multicellular creatures—some were likely worms as long as 40 cm—exposed new layers of seafloor sediment to the ocean's water. Each new batch of sediment that settles onto the sea floor contains bacteria; as those bacteria were exposed to the oxygen in the water, they began storing a chemical called phosphate in their cells. So as the creatures churned up more sediment layers, more phosphate built up in ocean sediments and less was found in seawater. Because algae and other photosynthetic ocean life require phosphate to grow, removing phosphate from seawater reduced their growth. Less photosynthesis, in turn, meant less oxygen released into the ocean. In this way, the system formed a negative feedback loop that automatically slowed the rise in oxygen levels as the levels increased.

mdsolar (1045926) writes in about a Norwegian team who believe they have an explanation about the unique distribution of HIV in Africa. "While around the world a vast majority of AIDS victims are men, Africa has long been the glaring exception: Nearly 60 percent are women. And while there are many theories, no one has been able to prove one. In a modest public health clinic behind a gas station here in South Africa's rural KwaZulu/Natal Province, a team of Norwegian infectious disease specialists think they may have found a new explanation. It is far too soon to say whether they are right. But even skeptics say the explanation is biologically plausible. And if it is proved correct, a low-cost solution has the potential to prevent thousands of infections every year. The Norwegian team believes that African women are more vulnerable to H.I.V. because of a chronic, undiagnosed parasitic disease: genital schistosomiasis (pronounced shis-to-so-MY-a-sis), often nicknamed 'schisto.' The disease, also known as bilharzia and snail fever, is caused by parasitic worms picked up in infested river water. It is marked by fragile sores in the far reaches of the vaginal canal that may serve as entry points for H.I.V., the virus that causes AIDS. Dr. Eyrun F. Kjetland, who leads the Otimati team, says that it is more common than syphilis or herpes, which can also open the way for H.I.V."

Nerval's Lobster writes "The remote-access management flaw that allowed TheMoon worm to thrive on Linksys routers is far from the only vulnerability in that particular brand of hardware, though it might be simpler to call all home-based wireless routers gaping holes of insecurity than to list all the flaws in those of just one vendor. An even longer list of Linksys (and Cisco and Netgear) routers were identified in January as having a backdoor built into the original versions of their firmware in 2005 and never taken out. Serious as those flaws are, they don't compare to the list of vulnerabilities resulting from an impossibly complex mesh of sophisticated network services that make nearly every router aimed at homes or small offices an easy target for attack, according to network-security penetration- and testing services. For example, wireless routers (especially home routers owned by technically challenged consumers) are riddled with security holes stemming from design goals that emphasize usability over security, which often puts consumers at risk from malware or attacks on devices they don't know how to monitor, but through which flow all their personal and financial information via links to online banking, entertainment, credit cards and even direct connections to their work networks, according to a condemnation of the Home Network Administration Protocol from Tenable Network Security. Meanwhile, a January 2013 study from Rapid7 found 40 million to 50 million network-enabled devices, including nearly all home routers, were vulnerable to exploits using UPnP. Is there any way to fix this target-rich environment?"
If only there were an easily upgradeable open source router operating system to which vendors could add support for their hardware leaving long term maintenance to a larger community.
